A milling cutter includes a body having three cutting edges formed by the body.
An end of the body situated opposite the cutting edges defines a fastening end
of the milling cutter. Each cutting edge extends from an outer periphery of the
body substantially to a center rotational axis of the body along a substantially
convexly curved path. Radially outer and radially inner ends of each cutting edge
are situated axially rearwardly of an axially foremost point of the cutting edge.
Each cutting edge lies on a respective imaginary sphere having a radius which has
a center which that is spaced from the cutting edge in a direction toward the fastening
end and spaced radially from the center axis.
